Point Counterpoint: MRI

Thomas P. Frye, DO, argues in favor of multiparametric magnetic resonance imaging (mpMRI) over micro ultrasound (MicroUS) for prostate imaging. He begins by stating the underlying goals of prostate imaging in the context of triaging in urologic oncology.

Dr. Frye then turns to the lack of data in support of microUS over mpMRI. He highlights that prostate imaging from MicroUS lacks the scale and reliable interpretability of mpMRI.

Dr. Frye supports the effectiveness of mpMRI in detecting clinically significant prostate cancer with data from the PROMIS and PRECISION studies. He notes that the use of mpMRI in screening can prevent unnecessary biopsies of insignificant cancers.

He concludes by reviewing weaknesses in recent studies of mircoUS. He presents a clinical analysis of microUS which demonstrated the superiority of conventional imaging (TRUS) and mpMRI over microUS.
